Abstract

PURPOSE:To eliminate the need for a special wired communication line by transmitting a switching control signal to a commercial power source circuit while using a frequency higher than a power frequency. CONSTITUTION:When operator operates an operation switch at a control terminal equipment 3, the information is combined into a switching signal and modulated by a carrier and sent to a controller 2 from a commercial power source circuit. The controller 2 controls the power supply of the controller 1 to be controlled according to its switch signal. The reply signal from the controller 1 is relayed by the controller 2 and sent to the commercial power source circuit. An equipment receiving the reply signal is provided to the terminal equipment 3 to supervise the start state of the controller 1 and the supervisory terminal equipment is connected to other commercial power supply circuit of the terminal equipment 3 to receive the reply signal and to display with supervision. Thus, the switching control signal is transmitted without providing a special wired information line.
